The IT Crowd creator Graham Linehan has announced on Twitter that the hit sitcom's farewell special will air later this month on Channel 4.

Chris O'Dowd, Richard Ayoade, Katherine Parkinson and Matt Berry will all return for the show’s final 40-minute episode.

Linehan first announced plans for a final IT Crowd special in December 2012, after previously confirming that the sitcom would not return for a full fifth season.

Linehan’s tweet is as follows: “People! I bring news! The IT Crowd Special will be on telly AT THE END OF THIS VERY MONTH! Channel 4 will have more details soon!”

The comedy - which originally aired between 2006 and 2010 - starred O'Dowd, Ayoade and Parkinson as three staff members of the IT department at the fictional Reynholm Industries.
